ANSI/SAIA A92.22-2020
Date of Publication: May 15, 2020
This Standard will become effective: June 1, 2020
This Standard was approved by the American National Standards Institute: May 7, 2020
The effective date is established by the standards developer and not by the American National Standards Institute.
This Standard was developed under procedures accredited as meeting the criteria for American National Standards
(ANS). The Consensus Committee that approved the Standard was balanced to assure that individuals from competent
and concerned interests have had an opportunity to participate. The proposed Standard was made available for public
review and comment which provides an opportunity for additional public input from industry, academia, regulatory
agencies, and the public at large.

American
National
Standard
Approval of an American National Standard requires verification by ANSI that
the requirements for due process, consensus, and other criteria for approval
have been met by the standards developer.
Consensus is established when, in the judgment of the ANSI Board of
Standards Review, substantial agreement has been reached by directly and
materially affected interests. Substantial agreement means much more than
a simple majority, but not necessarily unanimity. Consensus requires that all
views and objections be considered, and that a concerted effort be made
toward their resolution.
The use of American National Standards is completely voluntary; their
existence does not in any respect preclude anyone, whether he has
approved the standard or not, from manufacturing, marketing, purchasing, or
using products, or procedures not conforming to the standards.
The American National Standards Institute does not develop standards and
will in no circumstances give an interpretation of any American National
Standard. Moreover, no person shall have the right or authority to issue an
interpretation of an American National Standard in the name of the American
National Standards Institute. Requests for interpretations should be
addressed to the secretariat or sponsor whose name appears on the title
page of this standard.
CAUTION NOTICE: This American National Standard may be revised or
withdrawn at any time. The procedures of the American National Standards
Institute require that action be taken to reaffirm, revise, or withdraw this
standard no later than five years from the date of approval. Purchasers of
American National Standards may receive current information on all
standards by calling or writing the American National Standards Institute.

Foreword (This foreword is not part of American National Standard for A92.22-2020)
This standard is one of a series on Mobile Elevating Work Platforms developed under the committee
procedures of the American National Standards Institute. The accredited A92 standards committee was
organized by the Institute in 1948. The Scaffold & Access Industry Association Inc. serves as Secretariat.
The primary objective of this standard is to define rules for safeguarding persons and objects against the
risk of accident associated with the operation of mobile elevating work platforms (hereafter referred to as
MEWPs).
Interpretations and Suggestions for Improvement
All inquiries requesting interpretation of the Committee’s approved American National Standards shall be
in writing and directed to the Secretariat. The A92 Committee shall approve the interpretation before
submission to the inquirer. No one but the A92 Committee is authorized to provide any interpretation of
this standard.
All requests for interpretation and all suggestions for improvement shall be forwarded in writing to the
ASC A92 Committee, c/o Secretariat ~ Scaffold & Access Industry Association, 400 Admiral Boulevard,
Kansas City, MO 64106.
The A92 Committee solicits comments on and criticism of the requirements of the standards. The
standards will be revised from time to time when necessary or desirable, as demonstrated by the
experience gained from the application of the standards. Proposals for improvement of this standard will
be welcome. Proposals should be as specific as possible, citing the paragraph number(s), the proposed
wording, and a detailed rationale for the proposal including any pertinent documentation.
Revisions to A92.22-2022
The ANSI/SAIA A92.22-2020 contains revisions to eliminate Commercial Term
Violations. Further clarification on the revisions can be found at www.saiaonline.org/a92.
This Standard was processed and approved for submittal to ANSI by Accredited Standards Committee
A92 - Aerial Platforms. The ASC A92 Main Committee’s approval of the standard does not necessarily
imply that all committee members voted for its approval. At the time the ASC A92 committee approved
this standard, the A92 - Aerial Platforms Committee had the following members:

Introduction
This American National Standard is one of a series of standards produced by ANSI/SAIA A92 as part of its
program of work regarding standardization of terminology, ratings, general principles (technical performance
requirements and risk assessment), safety requirements, test methods, maintenance and operation for
elevating work platforms used to raise (elevate) and position personnel (and related work tools and
materials).
This Standard, ANSI/SAIA A92.22, along with companion Standards ANSI/SAIA A92.20 and ANSI/SAIA
A92.24, have been developed to replace existing Standards ANSI/SAIA A92.3, ANSI/SAIA A92.5,
ANSI/SAIA A92.6 and ANSI/SAIA A92.8. The reasoning that led to the development of these three new
Standards was: to combine the requirements for MEWPs exhibiting similar configuration and application; to
more closely harmonize with existing ISO Standards; and to more closely relate to a specific audience.

American National Standard for the Safe Use of Mobile
Elevating Work Platforms (MEWPs)
1. Scope and Purpose
1.1 Scope
1.1.1 Equipment Covered
This Standard specifies requirements for application, inspection, training, maintenance, repair and safe
operation of Mobile Elevating Work Platforms (hereafter known as MEWPs).
It applies to all types and sizes of MEWPs as specified in ANSI/SAIA A92.20 (design, calculations, safety
requirements and test methods) that are intended to position personnel along with their necessary tools and
materials, at work locations
Any MEWP covered by this standard is prohibited from use when working on or near equipment or circuits
which may be energized (see Section 6.8.12). The operation of any MEWP used for this work shall conform
to the requirements of the ANSI/SAIA A92.2 Vehicle Mounted Elevating and Rotating Aerial Devices
standard.
1.1.2 Effective Date
This standard will become effective June 1, 2020 for responsibilities for manufacturers, dealers, owners,
users, supervisors, operators, occupants, lessors, lessees and brokers for both new and existing units
delivered by sale, lease, rental or any form of beneficial use on or after that effective date.
1.1.3 MEWP Classifications
MEWP classifications are made up of a MEWP group (platform location in reference to tipping line) with an
associated MEWP type (reference to traveling).
Note: See definitions for Group and Type.
Training shall comply with ANSI/SAIA A92.24 Training Requirements for the Use, Operation, Inspection, Testing and Maintenance of Mobile Elevated Work Platforms (MEWPs) and shall identify both the group and type of the equipment for which training is provided.
NOTE See Appendix A for typical examples of equipment covered by each classification.
1.1.4 Applicability
This American National Standard is not applicable to:
a) permanently installed personnel-lifting appliances serving defined levels,
b) fire-fighting and fire rescue appliances,
c) unguided work cages suspended from lifting appliances,
d) elevating operator position on rail-dependent storage and retrieval equipment,
e) tail lifts,
f) mast-climbing work platforms (see ANSI/SAIA A92.9),
g) fairground equipment,
h) lifting tables with a lifting height of less than 2 m (6.56 ft.),
i) builder's hoists for persons and materials,
